Apologies for the hiatus also apologies if I've misunderstood the meaning of the Feedback status.

In general, "Feedback" means that an action of other than assignee is required.
In this ticket, I need a patch for backport which covers r33711, r33713-r33721, r33724, r33727,
r33728, r33752, and r33753.

I have a build error of ruby_1_9_3 branch at r37146 with mingw.
It seems due to r37138.
